The Strategy and Template Method design patterns are very similar, so much so that, just like with Factories, I would be very tempted to merge those patterns into a single Skeleton Method design pattern. I will resist the urge.
The difference between Strategy and Template Method is that Strategy uses composition (whether static or dynamic), whereas Template Method uses inheritance. But the core principle of defining the skeleton of an algorithm in one place and its implementation details in other places remain, once again observing the Open-Closed Principle.
